+#+TITLE: PROTOCOL: Skill - Project Foundry Agent
+#+STATUS: SIGNED

+
+* 1. Architectural Intent
+This protocol defines the shared Lisp interfaces for the Project Foundry skill. It ensures that every project in the Memex is instantiated with high structural and semantic integrity.
+
+* 2. Semantic Interfaces
+
+** 2.1 Project Scaffolding
+#+begin_src lisp
+(defun scaffold-project (name type)
+  "Physically creates the PSF project structure on disk and links it to GTD."
+  )
+#+end_src
+
+** 2.2 Trigger Perception
+#+begin_src lisp
+(defun trigger-skill-project-foundry (context)
+  "Determines if the current context warrants a project instantiation."
+  )
+#+end_src
+
+** 2.3 Proposal Verification
+#+begin_src lisp
+(defun verify-skill-project-foundry (proposed-action context)
+  "Validates the Neuro-cognitive proposal before physical actuation."
+  )
+#+end_src
+
+* 3. Integration with GTD
+The Foundry MUST append a new project entry to `gtd.org` using the standard PSF template, including `:PSF-STATE: A: DEMAND` and `:TRIGGER: next-sibling!`.
